Your 66 looks like a decent piece to work with. What you have there is a spring special package. Ford in spring of 1966 decked out some plain Galaxie 500's with some fancier trim borrowed from the XL and 7 Litre cars. Included were the chrome spear down the center of the hood versus no spear and the Ford crest emblem. Also, the lower quarter panel trim behind the rear wheels and also the fancy mag style wheel covers with the lugnuts sticking thru. Will be watching for more photos.
